Abstract

Methods of operation and interrupt controllers for generating interrupt signals to a unit, which could enter an active mode and a non-active mode, are disclosed. The interrupt controllers have interrupt logic (204) adapted for receiving requests for interrupt, activity mode logic (202) adapted for receiving information whether the unit is in non-active mode, and delay control logic (203) adapted for delaying the interrupt to the unit when the received information indicates that the unit is in non-active mode.
